I wonder if you could graft the f64 pack to a framed pack. REI has a number of reasonably priced packs that you can detach from the frame.

Mike, I use an adapted military surplus "Alice" pack frame for humping the heavy loads. You can easily attach an existing pack (or hard case for that matter w/ the available cargo shelf) with some compression straps and bungees. They are often available for a song on "that auction site". I see no reason why you couldn't easily adapt an f64 pack to it.
